Fullsized keybored: common questions

What microcontroller does the Fullsized keybored use?

The Fullsized keybored is built around the RP2040, from the RP2040/RP2350 family.

How big is the Fullsized keybored PCB?

The Fullsized keybored measures 428.6 × 123.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Fullsized keybored?

256 components, from 29 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Fullsized keybored design files?

From the calvin-mcd/vdf-fullsized-keybored repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Fullsized keybored design in my own project?

Yes, under the terms of its GPL-3.0 license, which calvin-mcd chose for the repository.

Can I test firmware for the Fullsized keybored without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
